High-Resolution Rotational Fourier-Transform Infrared Spectroscopy
(2022)2022 47th International Conference on Infrared, Millimeter and Terahertz Waves (IRMMW-THz)We demonstrate a rotational optical delay line for Fourier transform infrared (FTIR) spectroscopy with simultaneous high time and frequency resolutions. Thanks to the rotational motion, the trade-off between speed and spectral resolution present in rapid-scan FTIRs is alleviated, and enables the use of high-brightness quantum cascade laser frequency combs as light sources. We demonstrate the capabilities of the delay line by resolving ...Other Conference Item -
